f V'j Tofallwhorm it may concern: j

Be it known that I, WILLIAM CAMERON, a Y citizen of the United States, residing at Oak i 'G'I'Ove, in the county of Livingston and State Y i l of Michigan, have invented a new and useful i Shell, ofwhich the following is a specification. Y Y j It is the object of this invention to provide novel means for, operating or controlling the laterally movable knives of a projectile, and

` vto improve, generally, ,devices of the kind hereinafter described.Y I do not bind myself to theV specific construction shown in the drawings, because, within the scope of what yis claimed, a mechanic may make changes, without departing from, the spirit of the invention. Y v

In` the drawings Figure 1 is a side elevation; Figs.. 2 and 3 are longitudinal sections in rectangul'arly disposed planes; and Figs. 4 and 5 are cross sections, taken respectively on'the line 4-4 of Fig. 3, and 5-5 of Fig. 2.

The shell comprises a case 1 including a Ybody 2 on Vwhich is threaded a forward cap 3 and a butt cap 36, the cap 3 carrying a time fuse 4Y communicating with a container 5 carrying an explosive 6 and held in the cap 3 by a screw 7. Explosive containers 8 are located in the body 2 behind the container 5 and are held inthe body by screws 9; The Y,

. containers 8 areA connected' with the container 5 by time fuses 10. The container 5 ordinarily holds a bursting charge, whereas,

the'containers 8 may hold gas charges or the j like.

. The body 2 of the case has longitudinal forward slots 11 and longitudinal rear slots `12, the slots 1.1, and the slots 12, preferably slots 11 and 12. Forward knives 15 Operate in the slots l11,` and rear knives 16 operate in 'the slots 12. The lmives 15 and 16 are ful- 1 crumed intermediate their ends on the pivot Vmembers 14. There are longitudinal slots 17 inthe inner ends of the knives'and 16. A' Y A11-actuating memberV 18, in the form of a 4 fstrip or bar, moves longitudinally in the body 2. The actuating member includes a forward Ypart 19 extended between the inner endsof the vknives 15, and a rear part 20 *extended between the inner ends of the "knives 16, the parts 19 and 20 being disposed l' fat-right angles to each other and carrying `beingjlocated in planes which are at rightl f Vangles to each other. Pivot members 14 are mounted in the body 2 and extend across the projections 21 operating in theslot's 17 lof the' knives. Retractile -springs 37 are connected, each, at one end, to the forward part 19 of the actuating member 18, and aty their other ends are connected to the`body 2.

The part 19 of the actuatingmember 18 has a rack 22 in one edge engaged by a pinion 23 on a transverse shaft 24 supplied at one end with a reduced tip 25 journaled in a bearing opening 26 in the body 2 and forminga shoulder 27 which prevents the shaft from moving endwise in one direction. The body 2 is bulged inwardly to form a bearing 28 and an external recess 29; The shaft124 is journaled in the lbearing 28and the outer end of 4the shaft, which fprojects into the recess 29, has a seat 32 adaptedto receive a key. The shaft 24 is provided with a 'circumscribing groove 30, receiving the inner end of a retainer or pin 31 in the body, the shaft thus being held in the body for rotation but against endwise movement.

The body 2 supports a stud 33 on which is mounted a spring pawl 34 engaging the pinion 23, the pawl being provided adjacent its free end with a weight 35.

A key is inserted into the seat 32 and the shaft 24 is rotated, the pinion 23 meshing into the rack 22 and retracting the actuating member 18, the projections 21 swinging the knives 15 and 16 inwardly within the contour of the body 2, into the solid line positions of Fig. 2, the knives tilting on the pivot members 14. The pawl 34 engages the pinion 23 and holds the knives 15 and 16 retracted against the action of the springs 37. When the projectile is fired out of a gun, the rifling causes the projectile to rotate, whereupon, the weighted pawls 34,

vacting centrifugally, will be disengaged from the pinion 23. The actuating member 18 then moves forwardly responsive to the pull of the springs 37, until the outer ends of the knives 15 and 16 extend beyond the body 2, at an angle thereto, the inner ends of the knives abutting against the inside of the body 2, as shown in dotted line in Fig. 2. It will be obvious that the projecting knives will cut wire barriers and work havoc with anything which they may encounter.

1. A projectile comprisinga case; knives fulcrumed intermediate their ends on the case; an actuating member movable longitudinally in the case; means for connecting the actuating member with the inner ends of thev knives; means for moving the actuating member in one direction to advance the knives; means for moving the actuating member in an opposite direction to retract the knives; and centrifugally releas'abl'e means responsive to the rotation of the pro'-v jectile for holding the actuating member and the knives releasably retracted.

2. A projectile comprising a case; knives fulcrumed intermediate their ends onhthe case; an actuating member movable longitudinally in the case; meanskfor connecting the actuating member with the inner ends of the knives; means for advancing the actuating member and the knives; a shaft journaled in the case and accessible from the exterior thereof; coperating elements comprising a rack on the actuating member, and apinion on the shaft meshing into the rack; and a releasable holding device on the case and engagingy one of said coperating elements. .3. A projectile constructed in accordance with claim 2, andV further characterized by the fact that the holding device comprises an automatically releasable pawl on the case and engaging the pinion.

copies of this patent may be obtained f or A projectile constructed in accordance' with claim 2, and further characterized by the fact that the holding device comprises a Weighted paWl on the case and releasable A*by centrifugal action from that one of the said cooperating elements Wherevv'ithy theY pavvl engages.

5. Aprojectile comprising a case; Ya time fuse onfthe lforvvariil'end of the case; Van eX- plosive container in the case and responsive to the time fuse; secondexplosive containers in the case behindrthe first specified kcontainer; time fuses connecting 'the first` specified container with the second containers;

knives pivoted to the case and havingVV their inner ends operating between the second containers; means betvveenv the second containers vfor advancing the knives; V'and means for holding the knives retracted.
